论文摘要
这里表明，根据冯·诺伊曼（Von Neumann）的测量理论的佳能，对贝尔实验的最简单描述明确地假定了当地性的（量子力学语言等效）。该结果与最近发表的一个结果补充，表明在经典隐藏变量理论的框架内描述该实验是必要的，但是不必在量子力学的框架内描述它。总结这些和其他相关的结果，得出的结论是，在量子力学的框架内，绝对没有理由相信存在非本地效应。除了其基本意义外，该结论还对量子认证和与设备无关的随机性产生以及使用纠缠状态的量子密钥分布方案的安全性具有实际影响。
Here it is shown that the simplest description of Bell's experiment according to the canon of von Neumann's theory of measurement explicitly assumes the (Quantum Mechanics-language equivalent of the classical) condition of Locality. This result is complementary to a recently published one demonstrating that non-Locality is necessary to describe said experiment within the framework of classical hidden variables theories, but that it is unnecessary to describe it within the framework of Quantum Mechanics. Summing up these and other related results, it is concluded that, within the framework of Quantum Mechanics, there is absolutely no reason to believe in the existence of non-Local effects. In addition to its foundational significance, this conclusion has practical impact in the fields of quantum-certified and device-independent randomness generation and on the security of Quantum Key Distribution schemes using entangled states.
